LS series engines

We have several cost effective and power building CNC ported head packages for 4.8-6.2L Late model GM LS series engines for both catherdral and the later rectangle port L92 and LS3 heads. We also have several CNC combustion chamber programs as well as we offer chamber "softening" for nitrous or boosted appliations. This is a joint venture with our good friends at www.efituning.ca
